GAS-MACHINE.

SPECIFICATION forming part of Letters Patent No. 232,715, datedSeptember 28, 1880.

Applicationfiled January 15, 1880.

To all whom it vmay concern:

Be it known that I, ABEL HENNING, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented a new and usefulImprovement in Gas Apparatus, which improvement is fully set forth inthe following` 5 is a transverse section in line y' y', Fig. 2.

Fig. 6 is a vertical section in line .e z, Fig. 2.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a generator adapted to be heated, andcontaining a plunger which is subjected to the pressure of the vaporcreated from the hydrocarbon fluid injected into the generator and thusmoved, the effect where* of is to operate a pump which draws in a supplyof air, the vapor entering a chamber and coinmingling with said air,which is directed by suitable means to said chamber, from whence theresultant gas is passed out to a place of service.

It also consists of a valve automatically operated by the expansionofthe vaporizer when said vaporizer is overheated, and regulating theheating medium thereof.

It also consists of a burner for automatically igniting the heatingmedium ofthe vaporizer.

VIt also consists ofthe plunger having a valve for relieving it ofpressure and permitting it to rise in the vaporizer.

It also consists of mechanism for operating the feed-pump of thevaporizer.

It also consists of alink-connection between the shaft of the air-pumpand operating-lever, for preventing binding of the parts and causingsaid pump to move true.

Referring to the drawings, A represents a tank properly supported on atable or base, A', and B represents an air-holder, of the form ofacylinder or bellows, fitted within said tank, and having an air-inletpipe, C, and outlet-pipe D, and connected to itshead a vertical shaft,D', which passes freely through the base A and projects into a chamber,E, be

neath said base, and has connected at its lower end, by a hinged link,a, a swinging lever, F, whose fulcrum is on a suitable hanger, standard,or bracket, b, properly secured.

To the other end of thelever F is pivoted an 'upright shaft, G, whichpasses freelyy through the base A' and supports a plunger, H, locatedwithin the vapor or gas generating chamber J, consisting of a cylinderor shell closed at top and open at bottom, and supported on the base A',and having an inlet, c, for hydrocarbon fluid, said inlet communicatingwith a pipe, d, leading to a pump or other suitable feeding mechanism.

The chamber has a seat, c, for the plunger H, consisting of an innercylinder with perforations f communicating with the space between saidseat and the cylinder, whereby there is a communication between thechainbers J E.

The plunger H is adapted to rise and fall in the chamber J and cover anduncover the openings j of the seat e, and has a vertical duct orpassage, c', occupied in part by a valve, f', having a winged stem, sothat there is a communication between the top and bottom of the chamberJ through said plunger H.

The valve f' is held open by meansof a suitable spring properly appliedwithin the duct e' or elsewhere, and closed by the pressure of gas, ashereinafter set forth.

K represents a tank supported on the base A', and containing anair-holder of the form of a cylinder or bellows, L, within which projectan inlet-pipe, M, and outlet pipe N, the pipe M communicating wi th thepipe D of the holder B by means of a pipe, M', and the pipeNwith thechamber E by means of a pipe, N'.

Surrounding the chamber or generator J is a gas-jet, P, and adjacentthereto a gas-burner, P', both pipes of the jet or burner beingconnected to the valve of a gas-supply, E, the valve-head 7i' whereof isadapted to cover and uncover the communication of the pipe of the jet Pwithout similarly affecting the communication of the pipe of the burnerP', so that while the burner is constantlyignited the surrounding jet Pmay be shut off, the operation whereof' is automatical, as will behereinafter stated. y

S represents a lever which is mounted on a standard rising from the baseA', and has one end. bearing against the head of the valve R, its otherend-being jointed to a connection or arm, S', which is jointed to across-head, T, whose center rests freely on the pointed or rounded capT' at the top of the chamber J. Freely attached to the end of saidcross-head T, opposite to the arm S', is a connection or arm, U, whoselower end is jointed to the base A', said arm S' forming a fulcrum forthe crosshead T.

From the base A', adjacent to the tank A, rises a standard, A", on whichis mounted, by a horizontal axis, a disk or pulley, W, having a groovedperiphery for a weighted cord, Z, the object whereof is to rotate thepulley in one direction.

To the outer face of the pulley is secured a dog, W' whose head or noseis adapted to engage with the shoulder of a dog, X, Awhose lower end ispivoted to an arm, X',vwhose axis is on the standard A", and which hasits opposite end jointed to a toggle, X", the lower arm of which ispivoted to the holder B, sofas to rise and fall with it.

The upper end ot" the dog X is pivoted to the upper arm ofthe toggle X",and a spring, i, is connected to the arm X' and the lower end of the dogX.

v The pulley W has connected to it a cord, chain, or other connection,Y, of a pump-rod or other apparatus, for supplying the genera tor J Withhydrocarbon Huid, the return motion of the pulley being limited by aset-screw or screw-bolt, i', on the standard A".

The operation is as follows: The jet P is ignited and its flame heatsthe generator J, the burner P' also being lighted. A quantity ofhydrocarbon fluid is injected into the generator J through the pipe d,which may be accomplished by rotation of the pulley W by hand andconsequent operation of the pump. As soon as the fluid enters the hotgenerator J it is 'converted into hydrocarbon vapor, the pressurewhereof is immediately exerted on the plunger H, thus causing descentot" the latter, and by means of the shaft Gr, lever F, and shaft D' theascent of the holder B. Air is drawn through the pipe C into saidholder, the valve a' at the top of said pipe opening on the upwardmotion thereof.

The valve j" of the plunger is closed by the pressure of the vapor, andwhen the plunger descends below the openings f the vapor escapes throughthe latter into the chamber E. The valve f' then opens and the plunger,relieved of any remaining pressure, is free to rise, the descendingholder B, which being no longer cont-rolled. by the plunger H `andfalling by gravity, then causing the elevation of the plunger. In thismotion of the holder B the valve a' is closed and the air in said pumpis' forced through the pipe D into the pipes Ml M, and thus into theholder L, the Valve a" of said pipe M opening and said holder L rising.When the holder B has made its ascent the dog X is in such position overthe dog W' that when the dog X begins to descend it is brought intoengaging contact with said dog W'. W heny said holder B descends, andwith it the toggle X" and arm X', to which the dog lX is pivoted, thedog W' follows the motion lowest point the dog X is drawn clear of thevother dog, W', and the pulley W, owing to the weighted cord Z, returnsto its irst position, thus imparting an opposite motion to theconnection Y of the pump-rod, whereby another supply of hydrocarbontluid is injectedinto the generator J, which fluid is quickly convertedinto vapor, and the plunger H operated as before, thus again elevatingthe holder B. The valve a" of pipeM now closes and the holderL falls,thus forcing the air therein into the pipe N, and thus through the pipeN' into the chamber E, whcrle it unites with the hydrocarbon vapor, theresult being a serviceable gas which flows through a proper outlet tothe place of use. These operations are repeated and the supply of gasthus maintained.

The course of air is indicated by the arrows l and that of thehydrocarbon vapor by the arrows 2.

Should the metal of the generator l? be heated to an injurious orimproperly high tempera-ture the generator expands and raises thecross-head T, thus elevating the arm S' and lever S and closing thevalve R. The gas leading to the jetP is cut of without affecting the gasof the burner P'.

When the temperature of the generator is restored it contracts, thecross-headT and arm S' lower, and the valve R opens, thus againadmitting gas to the jet l?, which is ignited by the liame of the burnerP', and thus the generator is again heated. Should the temperature ofthe generator be insufcient the contraction of the same will cause thevalve R to be opened to a greater extent, and thus admit more gas to thejet until the temperature is restored.

The guiding-stem of the holder L is provided with a spring, b', whichbears against' the top of the holder and a suitable stop on the stem, sothat the ascent of the pump is not abrupt, and irregularity of the iiowof gas is prevented.

By means of the hinged link a, connecting IOO IIO

IIS

the shaft D' and lever F, there is no binding between said parts, andthe shaftD', and consequently the holder B, moves true at all times.

The arm X' may be connected to and operated by the holder L in order torotate the disk 5 but the position of the dogs requires to be reversedfor properly timing the action of the pump of the generator.

The joint of the toggle X" consists of a yoke formed on one limb or armand receiving a head on the other limb or arm. A screw, y', is

passed through the outer end ot' the yoke and bears against theaforesaid head, so that by the proper rotation of the screw the togglemay be lengthened or shortened relatively to the adjustments of the dogsX W.

I am aware that it is not new to operate a cut-off valve by theexpansive operation of .steam acting on a part of a metallic vessel.

I am also aware that it is not new to operate a pump by means of thedownward movement of a plunger in another vessel or cylinder andsuitable mechanical connections between said plunger and said pump.

I am also aware that a generating-chamber for vaporizing hydrocarbonfluid has been provided with an internal plunger, an external series ofheating devices, and inlet and outlet passages, and that the combinationof generating-chambers with expansible reservoirs or holders is notbroadly new. I do not claim the above devices. i

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. The generator J, having inlet c, in combination with plunger H,provided with valve f', internal cylinder e, having openings ff, and aheating device acting on said generator.

2. The combination of holderB,having stem D', with generator J, plungerH, rod G, and lever F, substantially as set forth.

3. The holder B, with air inlet and outlet pipes C D, the holder L, withair inlet and outlet pipes M N, the connecting-pipe M', the chamber E,generator J, plunger H, and lever F, combined and operatingsubstantially as and for the purpose set forth.

4. The air-holder B and pump-connection Y, in combination with thepulley W, having a dog, W', and the dog X, arin X', and toggle X,substantially as and for the purpose-set forth.

5. The plunger H and holder B, in combination with the lever F and shaftD', having the link-connection a, substantially as and for the purposeset forth. 4
